Animations of Six UV Ceti (flare) stars

Multi-epoch animations for six UV Ceti (flare) stars. Because they are red dwarf stars, the known UV Ceti stars are confined to the immediate solar neighborhood. Many such stars have relatively large proper motions. Among the UV Ceti stars, WX UMa has the largest proper motion -- over five arcseconds per year. This means that charts for these stars must be updated occasionally to reflect their changing positions.
